Working out at home is easier when your weights don't take up too much space. Adjustable dumbbells let you choose different weights, so you can build your strength using a single set.
But which ones should you buy? We've picked out options for different fitness levels - from compact sets for beginners to heavier weights for experienced lifters. We’ve also highlighted the best features to look for, and the additional equipment that can make home workouts even better.
How to choose the best adjustable dumbbells
Before you buy, think about the exercises you'll be doing and how much room you have. Here are the main things to check:
Maximum weight. Look at the limit per dumbbell, not for the pair. If you’re a beginner, you might be happy with 15–20kg per dumbbell. Experienced lifters will probably want more.
Weight increments. Smaller increases give you more flexibility as you get stronger. You can gradually add more weight as exercises become easier, rather than making a sudden jump that feels too challenging. Being able to adjust weight easily is also useful when training different muscle groups, as some exercises need less weight than others.
Adjustment mechanism. Adjustable dumbbells use different systems, including twist handles, dials and magnetic selector pins. Each works differently, so it's worth considering how easy you find it to change weights between exercises.
Grip and build. Look for comfortable handles, secure locking mechanisms and durable materials. Rubber-coated weights can also help protect your floor.
Dimensions and storage. Check the dimensions and bear in mind how much space you’ve got to store them. You can also check if a tray or cradle is included.
Adjustment mechanisms explained
Adjustable dumbbells use different systems to change the weight. Each has its own advantages, depending on how quickly you want to switch weights and how you prefer to use them.
Twist handle. Simply rotate the handle to select your preferred weight. The mechanism automatically adjusts the plates, so there's no need to remove or reposition individual weights. It's a straightforward way to change resistance between exercises.
Dial. Turn the dials at either end of the dumbbell while it's sitting in its storage tray. This selects the plates you need, leaving the others behind when you lift it. It's handy when you want to switch weights quickly during a workout.
Magnetic selector pin. Slide the magnetic pin into the slot that matches your chosen weight, then lift the handle. The selected plates come with you, while the others stay in the stack.
Best adjustable dumbbells for beginners and lighter workouts
If you're new to strength training, you probably don't need the heaviest weights available. A lighter set gives you room to practise your technique and build strength with controlled movements and higher repetitions. Here are some of the best adjustable dumbbells for beginners and lighter workouts.
Best compact adjustable dumbbells - PowerBlock Sport 24 dumbbells
Best for: Beginners and smaller spaces.
Pros
Adjustable from 1.4kg to 10.9kg per dumbbell
Magnetic selector pin for changing weights
Compact block design
Five-year guarantee
Cons
- 10.9kg maximum might limit heavier strength training
The PowerBlock Sport 24 dumbbells are a good choice for getting started with strength training. The plates are contained within one compact unit instead of extending out from both ends of a traditional dumbbell. This design makes it easier to store and helps prevent the plates from moving around while you exercise.
Each dumbbell adjusts from 1.4kg to 10.9kg, with a grip for a comfortable hold. That's enough for exercises like curls and shoulder presses, as well as lighter conditioning workouts.
Best adjustable dumbbells for beginners - StairMaster TwistLock dumbbells
Best for: Beginners and intermediate lifters.
Pros
10 weight settings per dumbbell
Twist-handle adjustment
Two storage cradles included
Cons
- Bulkier than a block-style design
The StairMaster TwistLock dumbbells adjust from 2kg to 20kg, with 10 settings to choose from. To change the weight, simply turn the handle while the dumbbell is sitting in its cradle. The 20kg maximum should be enough for most beginners, but people who need heavier training loads will want a set with a higher limit.
Best adjustable dumbbells for heavier strength training
If you're already lifting weights or want to work towards heavier presses, rows and squats, look for a set with a higher maximum weight. These options give you more resistance to work with as your strength develops.
Best adjustable dumbbells for mid-to-heavy training - PowerBlock Pro 100 EXP Stage 2 dumbbells
Best for: Intermediate lifters who want heavier weights.
Pros
Adjustable up to 27.2kg per dumbbell
Magnetic selector-pin adjustment
Compact block-shaped design
Five-year guarantee
Cons
- Shape might take some getting used to
If lighter weights aren’t enough for your workouts, the PowerBlock Pro 100 EXP Stage 2 dumbbells are a step up. They adjust up to 27.2kg per dumbbell and use a magnetic selector pin to change the weight. And that higher weight limit gives you more options for rows, presses and curls.
Best heavy adjustable dumbbells - Bowflex SelectTech 1090i dumbbells
Best for: Experienced lifters who want heavier weights.
Pros
Adjustable up to 41kg per dumbbell
17 weight settings
Storage trays included
Cons
- Bulky design
If you need serious weight for your home workouts, the Bowflex SelectTech 1090i dumbbells give you plenty of room to progress. Each dumbbell adjusts from 4kg to 41kg, with 17 settings selected using a dial. Their heavier maximum weight makes them suitable for exercises such as chest presses and rows. Just make sure you've got enough room to store them.

Are adjustable dumbbells worth it?
Adjustable dumbbells are a great way to build strength at home without filling a room with weights. One pair gives you several weight options, which potentially saves money compared with buying a few different pairs of fixed dumbbells.
They're bulkier than some fixed weights, and changing resistance can take a little time. But for most home workouts, the space you save makes them well worth considering.
Home workout essentials to pair with adjustable dumbbells
Dumbbells are a great start, and a few extra bits of kit can make your workouts even better. Here are a few ideas that can give you more ways to exercise and help track your progress:
A weight bench opens up more exercises, including chest presses, seated shoulder presses and supported rows. An adjustable design gives you more positions to work with. If storage space is limited, look for a foldable option like the Head HA369 foldable fitness bench.
A gym mat gives you a more comfortable surface for floor exercises and helps protect your flooring from scratches. It can also reduce noise when you're putting weights down.
A fitness tracker can help you keep an eye on your activity, heart rate and how often you're working out. Some models can also log strength-training sessions, giving you a handy record of your progress.

FAQs
Are adjustable dumbbells safe to use?
Yes, adjustable dumbbells are safe to use when they're assembled correctly and the weights are securely locked in place. Always check the selected weight before lifting, follow the manufacturer's instructions and avoid dropping them. Selector-style dumbbells aren't designed to withstand repeated impacts.
Can you build muscle with adjustable dumbbells?
Yes, you can build muscle with adjustable dumbbells by training your arms, chest, shoulders, back and legs. Increase the weight as you get stronger, and combine regular workouts with enough rest and a balanced diet.
How do you change the weight on adjustable dumbbells?
It depends on the design. Some models use a dial or twist handle, which you turn while the dumbbell is sitting in its cradle. Others use a selector pin that you move to choose the weight. Always check that the mechanism is properly engaged before lifting.
What's the difference between adjustable dumbbells and adjustable dumbbell/bar sets?
Adjustable dumbbells have built-in mechanisms that let you change the weight using a dial, twist handle or selector pin. Adjustable dumbbell/bar sets use removable plates, which can often be fitted to longer connecting bars to create a barbell. Changing weights usually takes longer.
Do adjustable dumbbells damage floors?
They can scratch or dent flooring if you drop them or put them down carelessly. A gym mat can help protect wooden or tiled floors and reduce noise. Avoid dropping adjustable dumbbells, as there’s a chance you could damage their adjustment mechanisms.
How long do adjustable dumbbells last?
With proper care, adjustable dumbbells can last for years. Keep the adjustment mechanism clean, store them in their tray or cradle safely. And check the manufacturer's guarantee so you know what's covered.
